6028-RS1/HC5 Bearing Product Overview & Core Advantages
The 6028-RS1/HC5 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This metric bearing is characterized by its sealed design and the use of advanced Silicon Nitride (Si3N4) ceramic balls, which significantly reduce friction and wear. Its primary advantages include high-speed capability, excellent radial load capacity, and long service life due to the hybrid ceramic-steel construction. The bearing is designed for applications requiring high reliability and precision under radial loads.
6028-RS1/HC5 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6028 | Standard deep groove ball bearing series with 140mm bore, 210mm OD, and 33mm width. |
| RS1 | Indicates a contact seal on one side, providing effective protection against contaminants. |
| HC5 | Signifies Hybrid Ceramic construction with Silicon Nitride (Si3N4) balls for superior high-speed and longevity performance. |
6028-RS1/HC5 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and Silicon Nitride balls reduces operating temperature, allows for higher limiting speeds (up to 4,000 rpm), and extends bearing life by minimizing wear and providing electrical insulation.
- High Load Capacity: With a dynamic load rating of 24,954 lbf and a static load rating of 24,279 lbf, this bearing is robust enough to handle significant radial loads in continuous operation.
- Sealed for Protection: The RS1 contact seal effectively shields the internal components from dust, moisture, and other contaminants, making it suitable for harsh environments without external lubrication (lubrication: None).
- Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance class with standard CN radial internal clearance, ensuring consistent performance and smooth operation.
6028-RS1/HC5 Bearing Typical Application Areas
This bearing is ideally suited for applications that demand high speed, reliability, and minimal maintenance. Key industries and equipment include:
- Electric Motors & Spindles: Especially high-frequency motors and machine tool spindles benefiting from the hybrid ceramic's high-speed capabilities.
- Pumps & Compressors: Where sealed protection and handling of radial loads are critical.
- Precision Instrumentation: Applications requiring smooth, low-friction rotation and long-term accuracy.
- Aerospace & Automotive Auxiliary Systems: For components operating at high RPMs where weight and performance are key factors.
